Here are some QG links that have been useful to have handy. Last time I updated the list was in July 2010. You can look back a few posts to the July list to find some which for brevity's sake have been omitted here.

Possible "textbook" resources:
Rovelli Upadhya (easy)
Rovelli Gaul (just relevant parts, short spinfoam section pp 43-46)
Baez handwritten lecture notes on spin networks/foams
Doná Speziale Introductory lectures to loop quantum gravity
Bojowald textbook (to be released) "Canonical GR and applications"
Renate Loll 3-week course at Perimeter, Intro to Quantum Gravity:
Baez on spinfoams (see especially pages 1-4 and 33,34)
Lewandowski et al on spinfoams
